Multiarch support seems to be incomplete

[devops-42]

Hi,

I tried to install the opentelemetry-operator via helm chart on a microk8s running on Apple M1:

helm install \
  opentelemetry-operator open-telemetry/opentelemetry-operator -n  opentelemetry-operator-system \
  --set manager.image.tag=v0.50.0

According to github the image used should be multiarch:
https://github.com/open-telemetry/opentelemetry-operator/pkgs/container/opentelemetry-operator%2Fopentelemetry-operator/21667125?tag=v0.50.0

Immediately after starting the pod crashes with standard_init_linux.go:228: exec user process caused: exec format error.

Do you plan to support the M1 architecture?

Thanks for your help!
Cheers

I am not familiar how docker/k8s multiarch works.

Did you try to use directly the image SHA for arm64 $ docker pull ghcr.io/open-telemetry/opentelemetry-operator/opentelemetry-operator:latest@sha256:32ecc752193cbbf049749f826a37a2dd8a08519e03619e869a8aa6e2abf1cfad from https://github.com/open-telemetry/opentelemetry-operator/pkgs/container/opentelemetry-operator%2Fopentelemetry-operator/21667125?tag=v0.50.0

Hi @pavolloffay,

yes, I tried to run a container from that image directly:

docker run --rm -ti ghcr.io/open-telemetry/opentelemetry-operator/opentelemetry-operator:latest@sha256:32ecc752193cbbf049749f826a37a2dd8a08519e03619e869a8aa6e2abf1cfad 
{"msg":"exec container process `/manager`: Exec format error","level":"error","time":"2022-05-09T16:56:47.000984445Z"}

The error will be shown immediately, the container crashes.

on my linux box I get a different message

docker run --rm -ti ghcr.io/open-telemetry/opentelemetry-operator/opentelemetry-operator:latest@sha256:32ecc752193cbbf049749f826a37a2dd8a08519e03619e869a8aa6e2abf1cfad               ploffay@fedora
